Abstract
This work aims to determine the resistance to abrasive wear of AISI 1010 and AISI C1064 steels used in tillage tools. For this purpose, computer simulation by the Discrete Element Method (DEM) was used, as well as experimentation in the field conditions of the Empresa de Cultivos Varios Manacas, located in the municipality of Santo Domingo, Villa Clara province, Cuba. The simulations included both the variation of the operating conditions of the tillage tool and the state of soil moisture and density. For the determination of abrasive wear, an experimental design with two treatments was developed, which were used to measure the mass loss depending on the material. The results of both simulations and experiments showed that the mass loss and geometry changes were much higher than 50% for AISI 1010 steel compared to AISI C 1064. On the other hand, it was corroborated that the DEM model used is capable of accurately predicting the wear experienced by the tillage tools subjected to wear (e=0.005g, R^2=99.8%), independently of the characteristics of the steels and the operating conditions. The mean absolute errors of the simulation with respect to the field tests reached 0.01937 g for AISI C1064 steel and 0.08619 g for AISI 1010.
